The answer for this is (-2,-4) because the x axis is horizontal so it on the other side ( see picture )
Substitute
, so that

Then the resulting ODE in
is separable, with

On the left, we can split into partial fractions:

Integrating both sides gives




Now solve for
:


if you're trying to solve for x, and it is equal to zero, then it would be -3. plug it in and it would all cancel out
Answer:
longer
Step-by-step explanation:
12 inches is a foot so you need to multiply 12 by 4 which gives you 48 so he needs 4 more inches to have enough string
